Rear Antenna “B” Input Connector: The “B” antenna can be installed directly to
this antenna connector which also provides power to an optional antenna booster.
Ventilation Fan: Ensures stable performance in long hours of operation under high
temperature environments.
Level Switch: "0dB" selection is for "Microphone level" output. "+16dB" selection is
for “LINE level” output. “-6dB” selection is for half of cable microphone volume.
Mixed AF Output Jack: A balanced output jack for mixed AF signals from all
installed channels; 3 output levels to choose from.
Balanced Audio Output Jack: XLR type connector provides balanced audio
output signal from this jack to the mixer, and output level is selectable from among 3

Unbalanced Audio Output Jack: ¼” PHONE PLUG type connector provides
unbalanced audio output signal from this jack to the mixer (ACT-71 only).
Output level is selectable from among 3 levels: “-6dB”, “0dB” and +10dB (the switch
will show +16dB on the receiver, but actually puts out +10dB on the unbalanced
jack).
Network Interface Connector: For linking the receivers to a computer system-
monitoring program.
Rear Antenna “A” Input Connector: The A antenna can be installed directly to this
antenna connector which also provides power to an optional antenna booster.
AC Power Socket: The input socket for AC power ranging from 100VAC ~ 240VAC.
Rack-Mount Brackets: To install the receiver into a standard EIA 19-inch rack case.
LIFT/GND Switch: Lifts ground from Pin 1 of the XLR connector. (GND = default).
